Introduction

Global business operations often require transferring personal data across borders, creating a patchwork of legal requirements that data centers must navigate. This is especially true when dealing with data subjects located in the European Union or other regions with strict privacy laws. This post examines key considerations for U.S.-based data centers handling cross-border data transfers and how to maintain compliance.

EU-U.S. Transfer Mechanisms

Although the Privacy Shield framework was invalidated, Standard Contractual Clauses (SCCs) remain a common tool for legal data transfers from the EU to the U.S. However, evolving case law around government access to data necessitates additional safeguards. Data centers should work with legal counsel to incorporate supplementary measures such as encryption, localized storage, or rigorous access controls.

Data Localization Laws

Countries like Russia and China impose stringent data localization mandates, requiring certain personal data to be stored within their borders. For U.S. operators serving clients in these regions, compliance may entail partnering with in-country facilities or exploring hybrid cloud solutions. Failing to adhere can result in service bans or steep fines.

Security and Encryption Standards

Strong encryption—both in transit and at rest—can alleviate concerns about unauthorized access. Data centers that demonstrate compliance with frameworks like ISO 27001 or SOC 2 also instill confidence among global clients. Logging and monitoring cross-border traffic with robust intrusion detection systems further reduce the risk of breaches and ensure prompt incident responses.

Contractual Obligations

Beyond SCCs, data processing agreements may require unique clauses for each jurisdiction. Addressing local regulatory nuances—like timeframes for breach notification—helps avoid noncompliance. Data centers should also clarify who manages data subject requests (DSRs) for access or deletion, ensuring that roles and responsibilities are well-defined across borders.

Conclusion

Cross-border data transfers involve a complex interplay of international regulations, requiring U.S.-based data centers to stay current on legal changes and implement robust security measures. By leveraging compliant transfer mechanisms, adhering to local data requirements, and drafting detailed contracts, operators can confidently serve global clients while minimizing legal risks.
